Specification of Letters Patent.

Patented NOV. 7, 1905.

Application filed March s, 1905. serial No. 249,087.

To all whom it may concern:

Be it known that I, WILSON NoLEs, a citizen of the United States ofAmerica, residing at Montrose, in the county of Lee and State of Iowa,have invented new and useful Improvements in Filters, of which thefollowing is a specification.

This invention relates to filters.

The objects of the invention are to improve and simplify theconstruction of such devices; furthermore, to prevent the porousfiltering medium from becoming broken bythe use of 1ce.

With the foregoing and other objects in View, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts vand in the details of construction hereinafterdescribed and claimed as a practical embodiment thereof.

In the accompanying drawings` forming part of this specification, Figure1 is a vertical section of a water-cooler and a filter constructed inaccordance with the invention. Fig.l 2 is a plan View of the filter.Fig. 3 is an under plan view of the filter. Fig. 4 is a detail view ofthe spacing-ring. Fig. 5 is a detail View of a bracket for holding thefiltering member in position.

Like reference characters indicate corre-l sponding parts in thedifferent figures of the drawings.

Referring to Fig. 1, the reference-numeral lV indicates a water-cooler,which may be of any suitable form and construction.

The improved filter of this invention is adapted to be placed inside thecooler l, as shown in Fig. l. The filter comprises a standpipe 2, whichis open at its upper end and is provided at its lower end with legs 3.The

lower end of the stand-pipe 2 is closed by means of a porous filteringmember 4, which is held securely in position by means of brackets 5.Disposed between the periphe'ry of the porous member 4 and the standpipe2 is a ring 6, of solder or cement, which serves to cause all the waterin the filter to pass through the porous member 4. Resting upon theupper surface of the porous member 4 is a spacing-ring 7 which is heldin position by means of brackets 8. A grating 9 rests loosely upon thebrackets 8.

The function of the grating 9 is to prevent the porous member 4 frombecoming broken by lumps of ice which may be dropped into the stand-pipe2.

Changes in the precise embodiment of invention illustrated and describedmay be made within the scope of the following claim without departingfrom the spirit of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is- Thecombination with a water-cooler, a filter fitted therein, said filtercomprising a stand pipe having legs, a porous filtering member in thelower end of said stand-pipe, brackets for holding said porous member inposition, a spacing-ring resting upon said porous member, brackets forholding said spacing-ring in position, and a grating removably supportedupon said last-mentioned brackets.

In testimony whereof I affix my signature in presence of two witnesses.

WILSON NOLES.
